CARBIOS, an innovative green chemistry company specializing in breakthrough technologies dedicated to the recovery of plastic waste, today announced that it has taken a major step forward with the validation of its in vivo enzymatic polymerisation process of lactic acid into a high-molecular weight homo-polymer of PLA.
On an industrial scale, current processes for the production of PLA require an expensive intermediary step consisting of the condensation of lactic acid (oligomerisation and cyclisation) into a lactid (a cyclic diester). This intermediary component must then be purified and chemically polymerized to obtain PLA (3D printing process).
The technological breakthrough brought by CARBIOS cuts out this intermediary step and produces, with greater competitiveness, a high-molecular weight homo-polymer of PLA directly from lactic acid. “My partners and I are proud to have successfully met this scientific challenge, and to have developed the first microorganism capable of producing a 100% PLA polymer of high-molecular weight,” says Alain Marty, Chief Scientific Officer of CARBIOS.
This milestone will enable CARBIOS to continue to the pre-pilot scale of this PLA production process within the initial deadline, thus allowing the possibility of considering potential agreements with industrials of the sector in the very near future.
